Skeptical? We tested hundreds of "flattering on everyone" shades on four women with very different skin tones. Here are the winners -- and the pictures to prove it

The expert says: "I like this shade on Stephanie. While the lipstick does have a blue base, it's pink enough to flatter Stephanie's yellow undertones. She can also apply Lancome Juicy Tube, $18, on top of the lipstick. It's a clear gloss that would really pump up the color and make her lips look more vibrant," says Nemes.

Stephanie says: "I was surprised it wasn't a little chalkier, because frosted lipsticks (like this one) tend to show up whiter against my natural lip color, but this is a true pink, so it looks great."
